[Clas12_rich] Mirror 5C-Autocad3D measurements

[Tomassini Sandro]

Hi Pablo

Thanks for your analisys. As you can see the outer radius is smaller than the inner one...
It should happen the contrary.
Next time we should distribute better the measured points on the mirror surface.
Have a nice weekend
